Notices 333 Power consumption Product power consumption The following table documents the power consumption characteristics of the product. Note: Some modes may not apply to your product. Mode Printing Description The product is generating hard‑copy output from electronic inputs. Copy Scan The product is generating hard‑copy output from hard‑copy original documents. The product is scanning hard‑copy documents. Power consumption (Watts) One-sided: 630 (CX730de, XC4342); 760 (CX735adse, XC4352) Two-sided: 520 (CX730de, XC4342); 640 (CX735adse, XC4352) 640 (CX730de, XC4342); 800 (CX735adse, XC4352) 44.5 (CX730de, XC4342); 45.0 (CX735adse, XC4352) Ready The product is waiting for a print job. 31.5 (CX730de, XC4342); 32.0 (CX735adse, XC4352) Sleep Mode The product is in a high‑level energy‑saving mode. 1.0 (CX730de, XC4342); 1.2 (CX735adse, XC4352) Hibernate The product is in a low‑level energy‑saving mode. 0.1 Off The product is plugged into an electrical outlet, but the 0.1 power switch is turned off. The power consumption levels listed in the previous table represent time-averaged measurements. Instantaneous power draws may be substantially higher than the average. Values are subject to change. See www.lexmark.com for current values. Sleep Mode This product is designed with an energy-saving mode called Sleep Mode. The Sleep Mode saves energy by lowering power consumption during extended periods of inactivity. The Sleep Mode is automatically engaged after this product is not used for a specified period of time, called the Sleep Mode Timeout. Factory default Sleep Mode Timeout for this product (in minutes): 15 By using the configuration menus, the Sleep Mode Timeout can be modified between 1 minute and 120 minutes, or between 1 minute and 114 minutes, depending on the printer model. If the printer speed is less than or equal to 30 pages per minute, then you can set the timeout only up to 60 minutes or 54 minutes, depending on the printer model. Setting the Sleep Mode Timeout to a low value reduces energy consumption, but may increase the response time of the product. Setting the Sleep Mode Timeout to a high value maintains a fast response, but uses more energy. Some models support a Deep Sleep Mode, which further reduces power consumption after longer periods of inactivity.
